tie it known that l, Flinn l). Bnnurr. a citizen of the United States, residin at lhihnlelphia, in the ount of Philadelphia and State of lennsylrauizh ha e in rented certain new and usel'ul linproid ments in AntitrictioirBearings. of which the following is a spw'itiration. reference heiirg had therein to the :nw-oinpairYing drawing.

This invention has J'Cttltlltt to hall hearings of the type in which two se 'ies it an nularl disposed halls are arranged between inner and outer casing lements in such luztliutir that the load sustained h) the hearing will he (list'rihuted between the two series oiballs.

The invention consists in a hearing of this type in which the casing elements are formed each as a single integral structure with uninterrupted and continuous hall tracks. and in which both series of halls may contain the full or substantially the tall numher or complement; whereby a unit-handling hearing is produced possess ins a maximum degree of strength and sup porting capacity, and in which, by reason .ot the continuous uninterrupted character of the ball tracks, the wear and friction will he reduced to a minimum.

Referring to the drawings: Figure l a side elevation of my ini iroved' bearing; Fig. 2 is a longitudinal section of the same; Fig, 3 is a transverse sectional elevation, showing the manner in which the halls of one series are introduced through the filling opening; Fig. 4 is a perspective view of a .form otspacing ca c which may he em ployed to maintain t 6 balls of the two se ries in spaced and staggered relations; Fig. 5 is a longitudinal sectional elevation on an enlarged scale, showing how the second series of balls are filled in on one side alter the insertion of the spacing; cage between the first series; Fig. 6 is a similar view with the spacing cage omitted. and showing the,

balls of the two series disposed opposite each other: and Fig. 7 is an edge View show ing how the balls of the first series are in troduced by longitudinal concentric displacement of the casing elements.

My improved bearing comprises an outer c sing element A, an inner casing element Specification of Letters Patent.

As shown more particularly in Fig. 0, the tendene; oi the load acting on the outer ring A, is to separate the two series of balls and cause them to apply outward (mp9 sitelyareting pressures on the inner ring: in the direction of the dotted lines 1/-- i3 formingthe inner ring as a single. integi xl structure, it is under these conditions, well adapted to recei\e and sustain the out- Yitl'tllY acting forces independently of any fastening or strengthening: means such as would he necesip where the V in e ringis tormedot ta'o loing'itinhnal sop-trawl parts to permit assrwnhlago m" the i in asseinhling the parts oi my improved h aring. \rhere hoth rings are integrah and in which hoth series at halls contain the tnll romplemenh the hall ol' ne series may introduced as shown in his 7.

By the method of assemblage :iliove ll"- sCl'il etl in minneclion with Fig. 7, it will ho observed that the filling opening is employed to introduce the balls to but one side of the rib on the casing element.

It will he observed that by reason of the rolative form and relation of the races on the two rings, the tendency of lhe loiul sustained by the bearing is to maintain the two series of balls outward beyond the edges of the filling opening, so that there will he no risk or liability of the acoirleuizil escape of the halls of either sorios when the hearing is in use.

novneos It will he observed that when thebearing assembled, with the two series of halls in place, the balls of one of the series act as 2 look to prevent. the parts of the hearing from separating. in addition to their load rnrrying fuuoiion While in the drawings l have shown the races (1', o 118 Hot. \liii'h i8 iho form l proffer lo adopt, they uniy. however, he curred without materially changing their Functions or action, the only requirement be ing' that the aces be inclined.

For rertain uses of the hearing, it is ilesirnl'ile that it he silent in operation, that (hat ihero he a a ice of the click eziuSed hy the halls contacting with those. in ad (HUGO as they are relieved of load. To meet this reouiren'ient and to secure other Well (-ruhle distance outward beyond the pomls known advantages i prefer to employ :1 spacing ring or czigzelogo maintain the halls of the lwo series in spoced relations. A form of cage for this purpose is represented in Fig. 4, and consists of'zi flat ring D having formed in its opposite edges, and alternately with each other, hall pocketso'r openings if, .rl". The ring is adopted to he iniroiliiced iulo the l'iei'n-ing' from the side and between thn halls of the ii st series after they have been assembled. The vacant spaces in the ring are then brought in sun session opposite the filling opening, and the halls passed through said opening: and scabod in the SPQCQS, the edges of whieh are bevvlerl as at (Z to pnrmit the halls to pass.

lhe result being that the halls of the two series will be spaced by lhe cage in staggered relations.

By the expression radial or radial or substantially radial used in the claims in describing the filling opening, I mean to include in addition to a filling opening ere lending in a strictly radial. direction on shown in the drawings, one which may he disposed in n. ion-oral radial direction, sueh for inslaneo as a filling" opening: somewhat inclined from the radial.

ills wing; thus described my invention, its

claim and desire to secure hy Letters Pat i. ent of the United States is follows: r rted to, provided the continuity of the 1 ruction and mode of operation, .What

between the ball races and leading to of them, and the edge 0 said fillin terminating at the sides and free 0 the lines of contact of the balls with the races; whereby the races are continuous and uninterrupted and the escape of the halls'is prevented.

2. in a ball bearing, the combination of inner and outer casing elements formed reepeeiivelywith races; and two series of interposed halls, one of the casing elements being provided with n filling opening situated between the two raceways and lending to both of them, the edge of which filling opening terminates at the sides and free of the lines of ball contact with the races, and the said raceways being so formed and disposed that the load on the hearing will act to urge the two series of balls away from the edge of the fillin opening; whereby the ball tracking sur aces arevcontinuous and unin both opening said elements, one

terrupted, and the accidental escape of the balls through the opening is prevented.

3. A ball bearing comprising inner and outer casing elements, each provided with two ball tracks forming two raceways between 2 of the casing elements being formed with a filling opening situated between the raeeways and leading to one of them, the edges of said opening terminating at the sides and free of the lines of contact of the balls with the raceways; whereby the ball tracks are continuous and uninterrupted and the escape of the balls is prevented.

In testimony whereof I have affixed my signature in presence of two Witnesses.
